What is the surface area of the figure?
408 ft², 458 ft², 545 ft², 720 ft²

Solution:

We have to find the surface area of the given figure.

Surface area = 2[(length × width) + (width × height) + (height × length)]

Now, 2(5 × 12) = 2(60) = 120

2(7 × 7) = 2(49) = 98

3(12 × 5) = 3(60) = 180

(7 × 5) = 35

(5 × 5) = 25

Surface area = 120 + 98 + 180 + 35 + 25

= 300 + 98 + 60

= 360 + 98

= 458 square feet.

Therefore, the surface area is 458 square feet.
